- PENNSYLVANIA.

ADJUSTABLE BIQRACKET.

srncrmon'rron forming art of Letters Patent No. 450,250, dated April 14, 1891. Application filed July 2, 1890. derial No. 357,522. (No model.)

To aZZ whom it may concern:

Be it known that we, ARNOLD NAGKE and ALBERT BRINKMANN, of Philadelphia, in the county of Philadelphia and State of Pennsyl- Vania, have invented certain Improvements in Adjustable Brackets, of which the following is a specification.

This invention relates to that class of fixtures, commonly used in pairs, which have arms to sustain horizontal rods on which the goods to be displayed are suspended.

The aim of the invention is to provide a cheap and simple construction which will per mit the arms of companion fixtures to be quickly adjusted to the same height and inclination.

In the accompanying drawings, Figure lis a perspective view of one of the fixtures in the preferred form. Fig. 2 is a vertical section through the standardand adjacent parts. Fig. 3 is a cross-section on the line 3 3, Fig. 1. Figs. 4 and 5 are views illustrating modified forms.

Referring to the drawings, A represents a standard, preferably tubular, fixed in position by abase-plate a or otherwise and provided at different heights with openings 0.

Bis a sleeve or collar arranged to slide upon the standard, and having a lip b, which may be seated in either of the openings at will to sustain the collar at different heights, as may he demanded. The collar is enlarged internally at the bottom in order that it may play laterally to a limited extent to permit the introduction of the lip to and its removal from the openings.

G is an outreaching arm having its inner end connected to an ear on the sleeve by a horizontal pivot c and provided with teeth 0 to engage a lip 11' on the sleeve, whereby the arm is maintained in the required position. The pivot passes through a backwardly and downwardly inclined slot 12 so that the weight of the arm tends to keep the parts engaged. This slot permits the arm to be lifted out of engagement with the lip, so that it may be turned upon the pivot to change its vertical inclination and then re-engaged in the new position. In order that the arm maybe adjusted in series to any given position, numerals d or equivalent indicating marks are formed on the arm in position to be read in connection with the locking-lip. These marks are applied to both sides of the arm, and the sustaining-arm skeletonized in order that they may be seen on one side therethrough. The openings in the standard are also numbered or otherwise designated to facilitate the adj ustment of the sleeve to a predetermined position.

Instead of forming the openingsin thestandard, they maybe formed in a rib or bar thereon, as shown in Fig. 4, the only requirement being that the sleeve shall interlock with the standard at different heights.

In some cases the sleeve may be provided with a set-screw, as shown in Fig. 5, asa substitute for the lip to hold it in position.

Having thus described our invention, what we claim is- 1. In combination with the arm, its sustaining-sleeve having a lip 19, and the standard provided with openings to receive the lip and sustain the sleeve.

2. The standard provided with the openings, in combination with the sliding sleeve having the lip to enter the openings, and having also the lateral ear, and the arm having the toothed end pivoted to and arranged to interlock with the ear, substantially as shown.

3. In a storefixture, the supporting -arm provided with teeth at its ends, in combination with the sustaining-ear having the lip Z) to engage said teeth, and the connection between the 'arm and ear, consisting of the pin. and the slot, inclined as described and shown, whereby the parts are caused to interlock and their engagement maintained without the assistance of springs or other adjuncts.

In testimony whereof we hereunto set our hand, this 24th day of June, 1890, in the presence of two attesting witnesses.

ARNOLD NAOKE.

ALBERT BRINKMANN.
